A company that provides identity protection services is sifting through the data released by hackers over the holiday weekend and they're detailing what hackers were able to steal from Stratfor, a security think tank.

If you haven't heard, hackers who claim an affiliation with the group Anonymous broke into the servers of Stratfor, made public some data and used some of the stolen credit card numbers to, in some cases, make charitable donations.

"Wired reported that someone who participated in the attack said that a total of four servers were breached, and the data on them wiped. The question that then logically arises is this: What was a firm that's ostensibly in the business of advising business and government clients on security doing about its own?"

"The disclosure was merely a list of some of the members that have purchased our publications and does not comprise a list of individuals or entities that have a relationship with Stratfor beyond their purchase of our subscription-based publications," the statement said.

Stratfor also advised its clients to keep quiet to avoid retaliation from the hackers.
